Project OverviewBondi Bikini Full Bust Adjustment (FBA)
Difficulty Level = Advanced Beginner / Intermediate
Our Facebook group is a great place to get help, share your tips and creations! We are a friendly bunch, and we love to help and see what you have made.
Please read the full instructions before getting started.
Wash, dry, and press your fabric before starting your project. A bit of prep now prevents shrinking and means your garment will stay the same size you made it.
Never leave a child or baby unattended or allow to sleep in a garment made from one of our patterns with ties, snaps, buttons, or anything they could remove, choke on, or get caught on. Always use caution if you are unsure. We love our patterns, but we love your bundles of joy more!
SizingSize Range

Fitting NotesTo get the best fit from your pattern you should go by your top bust measurement.
You will need to take 2 measurements when deciding which size is best for you:
You will need to make an FBA if the difference is 3 inches or more.
Here’s a guide to bust cup sizes:
Our ladies’ patterns are designed for a sewing C cup bust (B cup in most ready to wear bras). If you don’t fall into this size you may need to adjust your patterns, to get the best fit at the bust, armholes and across the back.
Materials and ToolsYou will need:
- + Instructions
1 . Trace your Pattern1.0
Trace the Outer Bodice piece, transferring all the pattern markings.
Cut the Outer Bodice piece from inexpensive swim fabric – with the same stretch/composition as your final swimsuit fabric. Try it on, pulling it up to the shoulder and under the bust. Mark the bust point (nipple) onto the muslin piece. Place this muslin over the original pattern piece and transfer the bust point marking onto the pattern piece.
NOTE – We recommend using a muslin piece to find the bust point as the pattern is designed with negative ease. This means the pattern piece won’t stretch across your bust and will make it difficult to find the bust point.
1.1You will now draw the lines you will use to split the pattern piece.
Draw a straight, vertical line (1) from the bust point to the bottom edge of the bodice piece.
1.2From the bust point draw a straight, horizontal line to the side seam (2).
1.3Using a flexible measuring tape, find the center of the armscye. Then find the quarter point between the center and the side seam. Draw a line from the quarter point to the bust point (3).
1.4Starting from right below the curve for the tie, draw a horizontal line to the bust point (4).
You will use these lines to split and spread the pattern piece.
2 . Split and Spread2.1Slip a piece of tracing paper underneath your pattern piece.
Starting at the bottom edge, cut along the line (1), through the bust point and along the line to the armscye (3), leaving a small hinge. Do not cut through the armscye.
Starting at the side seam, cut along the horizontal line (2) to the bust point, leaving a small hinge. Do not cut through the bust point.
Move the two pieces apart by the amount you need to increase the pattern piece by. Make sure you are keeping the pattern pieces parallel.
NOTE – We’ve used a 1 inch increase as the example in the photo. Please use your own required measurement here as this is where the fullness is added. An approximate guide is 1 inch per bust cup you need to increase by, however this will vary person to person. You may need to sew a muslin to check for your shape and then adjust further.
2.2Draw a new smooth bottom curve seam from the side seam.
2.3Cut the horizontal line between the center front and the tie curve (4), then drop the cut piece down to meet the bottom curve seam drawn in step 2.2.
Double check the measurement used in step 2.1 is still the same distance.
Tape all pieces onto the tracing paper.
2.4Starting from the tip of the tie, draw in a new line, following the original shape, down towards the bottom edge.
Tape all the pieces down onto the paper to secure and cut around the pattern piece.
3 . Closing the Side Seam3.1You will need to close the ‘dart’ at the side seam. Starting at the side seam, cut horizontally to the bust point, leaving a small hinge. Do not cut past the bust point.
3.2Starting at the bottom edge, cut up towards the bust pint, leaving a little hinge. Do not cut any further than the bust point.
3.3Close up the ‘dart’ at the side seam, moving the bottom piece up to match the edges together. Tape together.
3.4Place this new piece onto tracing paper. Draw a smooth line from each side of the gap you created above. Trace around this new piece.
Your FBA is complete! Use these new bodice pattern pieces to make a muslin (a test garment out of inexpensive fabric) to check the fit.
